Proc sql updating multiple columns
Then, a regular C/C compiler is used to compile the code and produces the executable. All SQL statements need to start with means later in the section on Error Handling.Host variables are the key to the communication between the host program and the database.Embedded SQL is a method of combining the computing power of a high-level language like C/C and the database manipulation capabilities of SQL. First, the Pro*C precompiler recognizes the SQL statements embedded in the program, and replaces them with appropriate calls to the functions in the SQL runtime library.It allows you to execute any SQL statement from an application program. The output is pure C/C code with all the pure C/C portions intact."NOT LIKE ANY" [Jan 2005 - 14 Posts] "Wrapping" a column in Bteq export [Feb 2009 - 2 Posts] %TYPE and %ROWTYPE equivalent in Teradata [Dec 2008 - 3 Posts] &sys* variables for fastload [Mar 2003 - One Post] 'Median' value of three dates [Mar 2013 - 6 Posts] ("1=1") condition in the explain plan [Dec 2004 - 14 Posts] (WM) Utility Throttle [May 2008 - 6 Posts] .compile bteq file location [Aug 2008 - 2 Posts] .

That was with the help of C# but now this time I am going to show, how you can insert and update image or varbinary field from within SQL Server itself.I have not been able to find the correct syntax for updating multiple fields in my 'master' data set with information from my 'infile' data set. more fields FROM MASTER MS LEFT JOIN INFILE IN ON MS. I tried this in vain: PROC SQL; UPDATE MASTER SET CITY = IN. Do a left outer join on the table you are trying to update, use your join fields, and update the value only where it is populated on the other table. DATA X; X = '1'; Y = 2; Z = 3; RUN; DATA Y; X = '3'; Y = 2; Z = 1; RUN; PROC SQL; CREATE TABLE Z AS (select CASE WHEN (b.x = ' ') THEN (A.x) else b.x END as X, a.y, CASE WHEN (b.z =.) THEN (A.z) else b.z END as Z FROM X as Aleft outer join Y as Bon A. Y ); QUIT; data lib.master(drop=rc); declare hash myhash(dataset: 'in.yourdata(rename=(cust_id=id cust_name=name))');*** ADD AS MANY VARNAMES AS YOU NEED ***; rc = myhash.definekey('ID','NAME'); rc = myhash.definedata('CITY','DATAVAR2','DATAVAR3'); rc = myhash.definedone(); do until(eof); set lib.master end = eof; call missing(CITY); call missing(DATAVAR2); call missing(DATAVAR3); rc = myhash.find(); output; end; stop; run; PROC SQL; UPDATE MASTER SET CITY = (SELECT INFILE.
The host variable declarations can be placed wherever C variable declarations can be placed.
